Thanks for reaching out about your migration issues and including great amounts of detail into the steps you’ve already taken. Form the notes you’ve provided we do see you’re running Confluence 6.1. This version of Confluence is no longer supported and we would suggest upgrading to a later support version (Currently at the time of this post we would suggest Confluence 6.5 or higher). Once you’ve upgraded your current system we would then ask you to reattempt the backup and restore for the migration.

just to understand this correctly: You want me to upgrade the system I am trying to migrate because I do not want to operate it any longer in order to migrate the newly upgraded system onto my container environment??

Is there any way for me to migrate the current 6.1 on-prem system into let's say a 6.5. container system?

We would suggest an in-place upgrade as you’re having issues attempting to migrate your instance. An in-place upgrade will allow you to bring your instance of Confluence up to a later version prior to the migration. This will offer a cleaner state as once you migrate it will be a simple migration vs a migration then multiple upgrades.

Since you’re having issues with the import portion of the migration and you’re wanting to upgrade as well then this path would be the best to attempt. There may be issues with the version you’re running which is causing the import to fail.

From your notes as well there is also an issue with using Confluence and MySQL Maria DB. Further information about this compatibility may be found at CONFSERVER-29060. When you’re ready to migrate please review the supported platforms linked in the initial answer to help find a supported database application.

Thank you for the response. I’ve reviewed the documentation provided again and can confirm MySQL is supported but variants, such as MariaDB, are not supported with Confluence. This is reported in the following:

You may attempt to export your Confluence 6.1 version into a later 6.4+ version. When doing this we would suggest you select a database from the following list (Here are the supported versions for Confluence 6.5):

Databases

PostgreSQL:

PostgreSQL 9.2

PostgreSQL 9.3

PostgreSQL 9.4

PostgreSQL 9.5

PostgreSQL 9.6

MySQL:

MySQL 5.6

MySQL 5.7

Oracle:

Oracle 12c (Release 1)

Microsoft SQL Server:

SQL Server 2012

SQL Server 2014

I hope this clarifies which databases are supported with Confluence.
